How could God insure that His goal for the earth and all mankind would work?  He had to make sure we had a part of his desire for good.

Genesis 1:26-27   “Then God said, “Let us make man in our image, in our likeness, and let them rule over the fish of the sea and the birds of the air, over the livestock, over all the earth, and over all the creatures that move along the ground. So God created man in his own image, in the image of God he created him; male and female he created them.”
